I also tried TinyMCE and it worked somewhat well. I had to add
to the plugin source so that TinyMCE keeps the linebreaks so that I don't need additional <br />-Tags.
The body of TinyMCE is also gray here. I remember fixing it for beta-3 but the changes got lost during the update to the final release. But I just played around with the global s9y-stylesheet until body and status line of TinyMCE were both white.
But as nice as TinyMCE is, I got a bug ... and I don't know whether it is a problem with Opera or with TinyMCE itself. Sometimes it creates instead of a simple space. Of course, this creates a very weird look.
Did anyone notice this, too? I'd love to use TinyMCE but currently, I'm spending more time afterwards correcting all those than with actually writing an entry.
Cheers,

EDIT: Thinking about it, it may have to do with the AutoSave-plugin. Maybe reading the contents of the fields for saving interferes with some TinyMCE-stuff or confuses the browser ... I don't know. Will play around with it when writing my next entry.
